It will be the second large bridge project connecting Alstenoya to the mainland, ing more than 12 years after the Helgeland Bridge was opened. The region is no stranger to worldrecord scale bridges ?the Helgeland Bridge39。****大學(xué)畢業(yè)設(shè)計（論文） 1 Long and light—— 《 Bridge design amp。 engineering》 Closure of the main span on the Sundoya Bridge in Norway is expected to take place in the first week after Easter. This graceful crossing, the second longest of its type in the world, is being built in situ using high performance concrete Sundoya Bridge is situated in one of Norway39。s 425m long main span was the longest cablestayed span in the world when it opened in 1992. Sundoya Bridge is divided into three spans。s three. Contractor AS Anlegg, which is part of the joint venture building Sundoya, was also the contractor on the Raftsundet Bridge, and architect Boarch Arkitekter has also worked on the two schemes. In January 2020 the joint venture pany AF Sundoybrua won the contract from client Statens Vegvesen to build the Sundoya Bridge. This joint venture consisted of the contractors Reinertsen Anlegg and NCC Construction. High performance concrete is central to the design of the bridge ?both normal weight HPC and lightweight HPC. Normal weight concrete, at approximately 2500kg/m3, is used for the 120m side spans, while lightweight concrete, which weighs in at about 1970kg/m3, is used for construction of the 298m main span. This enables construction to proceed using the balanced cantilever method. Local rock from Norway is used as the aggregate for the normal weight concrete, but the lightweight concrete required an imported solution. Normally the aggregate used for lightweight concrete in Europe is expanded clay or shale, but this material has high levels of absorption and for this reason, regulations prevent such concrete from being pum
